A Burlington, Ont. 13-year-old girl is facing poisoning and weapons charges after allegedly hosting the sleepover from hell.

The victim, another 13-year-old girl, was at a sleepover at the accused’s house last Saturday when she reported waking up covered in bleach. As she came to, the accused threatened her with a knife while continuing to splash more bleach at her.

The abuse continued into the following day as “the victim was physically assaulted by the accused on more than one occasion,” read a release by the Halton Regional Police.

On Wednesday, police announced that the accused had been charged with administering a noxious substance, assault, assault with a weapon and possessing a weapon for a dangerous purpose. Her name cannot be released under the provisions of the Youth Criminal Justice Act.
